You have joined hundreds of thousands of other satisfied Galaxy customers. Since 1977 Galaxy Audio s professional experience in design and manufacturing ensure our products quality, performance and reliability. For users who need an advanced UHF wireless system, the DHX and DHXR4 provides an excellent solution. With 10 selectable channels, they are perfect for applications such as live shows, broadcast, meetings, & musical instruments. Touch buttons and liquid crystal displays allow for a quick and simple system setup. The Quick Start Guide included in your system will provide all the details you need to operate the system efficiently. Frequency Band Most countries closely regulate the radio frequencies used in the transmission of wireless information. These regulations state which devices can use which frequencies, and help to limit the amount of RF (radio frequency) interference in all wireless communications. The DHXR4 offers 10 selectable channels within either the 584-607MHz (Code D), 655-679MHz (Code L) or 518-55MHz (Code N) frequency ranges. To facilitate system setup and protect against RF interference, each system comes with multiple predefined frequency groups and channels. When using a single receiver/transmitter, the operating frequency will generally not have to be changed. In an installation with multiple receivers/transmitters, each set must operate on a separate channel from the others. The group and channel system provides an optimum frequency spread when using multiple receiver/transmitter systems.

The higher level will reduce the useable distance of the transmitter from the receiver. Use the lowest setting that keeps the receiver quiet when the transmitter is off. The DHXR4 now utilizes Tone Key Squelch. This keeps the receiver channel muted until it receives the inaudible tone from its transmitter. This keeps the channel quiet when the transmitter is off, even if something else is transmitting on the frequency on which the channel is set. 6

POWER UHF Four Channel Diversity Wireless Receiver Setting Up Multiple Receivers Using the auto scan function to find clear frequencies for your DHX or DHXR4 System 4 4 1) Power on any pre-existing wireless systems and transmitters (excluding DHXR/DHXR4). ) Power on the DHXR/DHXR4 Receiver, do not turn on the DHXR/DHXR4 transmitters. ) On the DHXR or the first channel of the DHXR4, press the button until scan flashes, then press either the up or down button. The receiver will then scan for an open frequency channel within the group selected, and stop on the frequency. When the DHXR4 Receiver has been set to a clear frequency, use the /ASC feature to sync the receiver frequency to the transmitter. 4) Power on the transmitter for the DHXR or the first channel of the DHXR4, and sync it to the receiver using the /ASC feature. Turn the transmitter on and aim its IR window towards the IR SYNC window at the left side of the DHXR/DHXR4, then press the /ASC button on the desired receiver channel, and the transmitter will automatically set to the receiver s frequency. 5) For using more channels on the DHXR4, leave the first channel transmitter on and repeat steps and 4 for the second DHXR4 channel. 6) Continue this process for the rd and 4th channel of the DHXR4. 7) If the receiver is unable to find open frequencies on the group selected, you will need to set one or more receiver channels to another group, and then scan again. 8) To change the group, press the button twice, the group number will begin to flash. Use the up or down button to select another group. Then proceed as before. 9) If you have more than one DHXR or DHXR4 system, continue the process as described, adding one channel at a time. If you have more DHXR or DHXR4 systems to tune follow the same procedure on each one, always leaving the previous system transmitter on. 1
Tips for Improving System Performance Troubleshooting Maintain a line of sight between transmitters and antennas. Avoid placing the receiver near metal surfaces or any digital equipment (CD players, computers, etc). Keep the receiver away from the wall and at least 1m from the ground. Cellular telephones and two-way radios can interfere with the operation of wireless systems. Do not use these devices in close proximity to the wireless systems. Troubleshooting Issue Indicator Status Solution No sound or faint sound. Transmitter LCD off. Receiver LCD off. Receiver indicates RF. Turn on transmitter. Make sure the batteries are installed correctly. Make sure AC adapter is securely plugged into electrical outlet and into DC input connector on rear panel of receiver. Increase receiver volume. Make sure Gain adjustment switch on the transmitter is set correctly (applies only to MBP77 Body Pack.) Distortion or unwanted noise. Distortion level increases gradually. Sound level different from cabled guitar or microphone, or when using different guitars. Receiver indicates No RF, Transmitter LCD is on. The battery power indicator light on LCD flashes. Receiver Indicates RF. Transmitter power indicator light flashing on the LCD. Make sure Transmitter and Receiver are set to the same frequency. Make sure Transmitter is in range of Receiver. Make sure no large metal objects are near Transmitter or Receiver. Change the batteries in transmitter. Remove nearby sources of RF interference (CD players, computers, in-ear monitor systems, etc.) Use Auto Scan to find a clear Channel Replace Transmitter batteries. Adjust Transmitter Gain and Receiver Volume as necessary. 1

To be assured of the best performance, you should determine on what RF channels the DTV stations in your area are broadcasting, then set your wireless systems on frequencies that are not being used. You can find that information on this FCC web site. https://www.fcc.gov/media/engineering/dtvmaps Enter the zip code of the location where the wireless system will be used into the location search bar. A list of stations in that area will be listed. Click on the call sign of the stations and the details will appear, showing you the RF channel the TV station is using. Compare these with the chart to the left, and using the Galaxy frequency charts on page 16, find a frequency that is not on an active DTV RF channel. For example, if you have an L-Band DHXR and your location has DTV stations on RF channels 45 and 48, you will want to set your DHXR on a frequency that is on RF channel 46 or 47. FCC Consumer Alert for Wireless Microphones (U.S.) Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC's wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones Please visit galaxyaudio.com for the latest updates 17
